3M™ Scotch-Weld™ Epoxy Adhesive 2216, Gray, Part A, 55 Gallon (50 Gallon Net), Drum

When selecting a Duo-Pak (DP) size adhesive, utilizing 3M dispensing equipment ensures dependable and precise metering, mixing, and dispensing capabilities. This specialized equipment is engineered to optimize the application process and deliver consistent results across various industrial bonding tasks.

The 3M™ Scotch-Weld™ Epoxy Adhesive 2216 represents a premium solution for applications demanding high-performance flexible bonding characteristics. The inherent flexibility of this formulation makes it particularly well-suited for bonding dissimilar substrates and scenarios where different materials exhibit varying coefficients of thermal expansion. Upon complete curing, this epoxy adhesive creates an exceptionally robust bond that maintains its integrity during thermal expansion and contraction cycles, as well as under conditions involving limited substrate movement. Additionally, the adhesive demonstrates excellent long-term strength retention and exhibits remarkable resilience following environmental aging exposure.

Formulated with a 2:3 mix ratio, this low-viscosity epoxy flows effortlessly for precise application. The base and accelerator components are distinctly color-coded in contrasting hues, providing clear visual identification of each product component during the mixing process.

The 3M™ Scotch-Weld™ Epoxy Adhesive 2216 has been specifically engineered to perform reliably in extremely low-temperature environments. With the capability to withstand temperatures as low as -423°F (-252°C), this adhesive is ideally suited for demanding cryogenic bonding applications. At standard room temperature, the adhesive provides an extended 90-minute working window, allowing adequate time for component repositioning and fine adjustments. While the adhesive naturally cures over a seven-day period, heat-acceleration methods can reduce the curing time to approximately 30 minutes when applied at 200°F (93°C). The cured adhesive achieves impressive bonded shear strength, capable of withstanding loads up to 3,200 psi at 72°F (24°C).

Epoxy adhesives, including rapid-cure five-minute formulations, belong to the broader category of "structural adhesives," which encompasses polyurethane, acrylic, cyanoacrylate, and related compounds. These adhesives are formulated as liquid reactive polymers that undergo controlled chemical reactions when their components are combined, ultimately curing into solid plastic materials. Once the two components are mixed according to their specified proportions, an irreversible curing process commences, during which the adhesive maintains workability for a defined period. This working time window can range from just a few minutes to several hours, depending on the specific formulation. Structural adhesives of this category deliver substantial shear and peel strength characteristics, along with superior heat and chemical resistance compared to conventional adhesive options. Epoxy adhesives generally demonstrate the highest overall strength among adhesive categories and offer exceptional performance, high-temperature resistance, solvent resistance, and outstanding durability against outdoor weathering conditions.

Epoxy adhesive, commonly referred to as epoxy glue, has become indispensable across numerous industrial and consumer sectors. These products are widely utilized in building and residential construction projects, automotive manufacturing operations, and the assembly of bicycles, boats, golf equipment, skis, and snowboards. The versatility of epoxy adhesives extends to countless other applications wherever robust bonding performance is required in conjunction with environmental condition resistance. These products have gained widespread acceptance due to their user-friendly application methods, exceptional mechanical strength characteristics
